2.4lbs is pretty good for a muffler. Do you have any straight through designs for a build it yourself muffler. I like what you did but I think it would have more flow resitriction than a straight through design.

2.4lbs is damm light, lol

Some time ago I installed a straight thru muffler on my semi. It had about 3-4 doughnut style baffles all with a 5 inch open center. I seriously could have dropped a softball right thru. It was very quiet. From the time I hit second gear(out of 13) I could tell the power was off. I couldnt pull a load anything like before and did a lot more shifting. In the 5 days that muffler was on I spent $147 EXTRA in diesel fuel. Needless to say Id rather put up with the noise than pay the extra in fuel and lost time.

Live and learn I suppose...Im also interested what that aluminum one you just finished sounds like.

I wouldnt worry so much about what the welds look like, as long as it holds...At least for that part. The only time someones going to see it is if you flip your car on the track, and I dont think that someone pointing out your welds would bother you more than other things at the same moment...just my .02.

Nice weight drop though...definitely a good way to pick up your time.

Precision is only as important as the project...if you're building a rocket ship...1/64" would matter. If you're building a sledgehammer...an 1/8" probably wont.

Well, gained 2 mph!!!!! Lost et, but that was because the track was cold, I launched low rpm and bogged, my 60' was horrendous @ 1.62. Im stoked, problem is I broke My transmission right after. Tired to do back to back runs vs open headers, but she broke...
